Which of the following material has lest value of thermal diffusivity?
A)Aluminium
B)Rubber
C)Lead
D)Mercury
E)Iron

Question

Quizplus · Accepted Answer

Rubber has the least value of thermal diffusivity among the options given. Thermal diffusivity measures how quickly a material can conduct thermal energy relative to its ability to store thermal energy. Metals like Aluminium, Lead, Mercury, and Iron generally have higher thermal diffusivities due to their good thermal conductivity. Rubber, being a poor conductor of heat, has a much lower thermal diffusivity.
